I think your reply would have been a lot more persuasive without "As someone who actually goes to a top school..."

It sounds like bragging. And worse: it doesn't do anything for your argument.

(And for the record, I agree with you.)

It gives him somewhat more direct insight, having experience with what such students are like. He clearly meant it in that light. What would he possibly get from bragging? (People who go to top schools are a dime a dozen, after all. ;-)
